Smog help
Need help with my smog numbers.
15mph reading max 25mph reading max
hc 278 86 344 86
co 5.92 .73 5.65 .73
no 530 711 425 711
This is an 88 with a brand new engine, new o2 sensor, new temp sensor, air temp sensor is testing good, new map sensor.
Anyone have any ideas why this numbers are so bad? I have changed everything I can think of besides that cat. The motor has about 30 mins if run time on it and the spark plugs are black.
